Homicide remains an endemic, seemingly unsolvable problem in America. And violent crime afflicts African-American communities to a much greater degree than it does others, as does mass incarceration — and as does police violence. What is the cause of this crisis?

And you can weigh in — thanks to the special addition of Bing Pulse audience response technology, which will track your opinions on the discussion in real time during the conversation.
